Soft aurora borealis slowly flowing across the night sky. Gentle green and turquoise light curtains move with very subtle, continuous wave-like motion, repeating evenly without progression. The movement is calm, smooth, and breathing-like, clearly visible but minimal. The reflection on the water softly ripples in sync with the sky, maintaining vertical symmetry. Static camera, locked position. No zoom, no cuts. Designed for a seamless loop where the motion naturally repeats.
